Передача входных значений формы из строки запроса приводит к пустым атрибутам

Question

Я пытаюсь передать данные из одного приложения в другое, используя строку запроса со ссылкой:

domain-example.com/authorizations/new?name=Some%20Name&email=email@server.com&type_of_booking=DEP&booking_id=101&price=1001

Я успешно получаю значения из строки запроса ввходные данные формы, но при отправке формы значения остаются пустыми в базе данных.

Контроллер также внес атрибуты в белый список.

Вот мой код.Что здесь может происходить?

_form.html.erb

<%= form_with(model: authorization, local: true) do |form| %>
  <div class="field">
    <%= form.hidden_field :name, value: params[:name] %>
  </div>

  <div class="field">
    <%= form.hidden_field :email, value: params[:email] %>
  </div>

  <div class="field">
    <%= form.hidden_field :type_of_booking, value: params[:type_of_booking] %>
  </div>

  <div class="field">
    <%= form.hidden_field :booking_id, value: params[:booking_id] %>
  </div>

  <div class="field">
    <%= form.hidden_field :price, value: params[:price] %>
  </div>

  <div class="actions">
    <%= form.submit %>
  </div>
<% end %>

authorizations_controller.rb

class AuthorizationsController < ApplicationController
  before_action :set_authorization, only: [:show, :edit, :update, :destroy]

  # GET /authorizations

  def index
    @authorizations = Authorization.all

      else
        format.html { render :edit }
        format.json { render json: @authorization.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /authorizations/1
  # DELETE /authorizations/1.json
  def destroy
    @authorization.destroy
    respond_to do |format|
      format.html { redirect_to authorizations_url, notice: 'Authorization was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_authorization
      @authorization = Authorization.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def authorization_params
      params.require(:authorization).permit(:name, :email, :type_of_booking, :booking_id, :price)
    end
end

Не используйте attr_accessor для атрибутов базы данных в ActiveRecord.

Он не только полностью лишний, но и переопределяет методы получения и установки, которые ActiveRecord создает из вашей схемы базы данных, которые необходимы для правильной работы AR.

Конечный результат, как вы можете видеть, состоит в том, чтомодель просто берет атрибуты и ничего с ними не делает.Точно так же, как переменные экземпляра простого старого объекта ruby.

Также вы должны связать атрибуты в вашем контроллере, а не в форме, так как вы непреднамеренно нарушаете форму (устанавливая входные значения равными nil), когда она отображаетсяиз действия создания.

class AuthorizationsController < ApplicationController
  before_action :set_authorization, only: [:show, :edit, :update, :destroy]
  # ...

  # GET /authorizations/new
  def new
    @authorization = Authorization.new(
      params.permit(:name, :email, :type_of_booking, :booking_id, :price)
    )
  end
end
